IMPROVEMENT IN RAILROAD-SIGNALS.

Specification forming part of Letters Patent No. 152,870, dated July 7,1874; application filed May 29, 1874.

panying drawings and to the letters of reference marked thereon, makinga part of this specification.

The nature of my invention consists not so much in any specific device,as in the combination and arrangement of certain levers and cranks witha bell and with a railroadtrack, for the purpose of giving an alarm atcrossings, as will be set forth.

In the annexed drawing, which is a perspective view of my invention, AArepresent the rails of a track. As the train passes backward and forwardon this track, the wheels of the car strike one end of a crank-lever,(J, for the purpose of giving an alarm. This lever 0, it will be seen,bends and passes under a block, B, close by the side of the track, whichconfines it in place. One end of it lies close to the rail, so that thecarwheel can easily strike it in passing, and to the other end isconnected a spring, D, which stands in a vertical position, with itsupper end resting in a loop in the upper end of a standard, J. E and Grepresent two levers, one pivoted to the standard J, and the other to apost, K, and both at their centers. F 1 represent two rods, whichconnect these levers together, holding or fastening into theirextremities. A loop, d,

on lever E passes over the spring D, andconnects it with said lever. Theupper end of lever G connects to an arm of a crank marked H, which isconnected to the upper end of post K, as is clearly represented in thefigure. The crank H bears a hell, I, which rings when suit= able motionis imparted to it.

When the car-Wheel strikes one end of crank C, said crank moves thespring D, which, in turn, oscillates the lever E by means of loop 01,and lever E, operating upon lever G through rods F, oscillates lever G,and this lever, act ing on crank H, partially rotates it and thus causesthe bell to ring.

Thus an automatic signal is given at each crossing on the road.

The spring D answers the purpose of returning the lever or crank O to anupright position immediately, so that it will be in condition to beoperated upon by the next passing train.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The crank 0, spring D, levers E G, rods F F, and crank H, bearing thebell I, in combination with the rail of arailroad-track, as and for thepurpose herein specified.

In testimony that I claim the foregoing I have hereunto set my hand this11th day of May, 1874.
